Convergent Continent-Ocean Plate Boundary Occurs when an ocean plate collides with a continental plate The ocean plate will ALWAYS go underneath the continental plate The process of the ocean plate going underneath a continental plate is called - SUBDUCTION

5
What kinds of Earthquakes occur at an Convergent Continental-Ocean Boundary? Along the subduction zone there will be: –shallow EQ’s –intermediate EQ’s –deep EQ’s All these EQ’s occur along a 45° angle

Convergent Ocean-Ocean Plate Boundary Occurs when an ocean plate collides with another ocean plate The most dense ocean plate will ALWAYS go underneath the less dense plate The process of an ocean plate going underneath another ocean plate is called - SUBDUCTION

8
What forms at a Convergent Ocean-Ocean Boundary? Ocean trenches Subduction zone for plate melting Magma chamber from melted plate Oceanic Volcano above magma chamber A series of new islands called an Archipelago or an Island Arc –an archipelago is a chain of volcanic islands

Convergent Continent-Continent Plate Boundary Occurs when a continental plate collides with another continental plate The two continents deform because of the collision Both plates are bent up and down

Transform Fault or Side-by-side Plate Boundary Occurs along a crack in a tectonic plate Each plate will slide past one another
